Shinji Itou

Just like Mitsuhashi, Itou got transferred to Nanyou High's first year. Being a complete reversal of Mitsuhashi, Itou's the kind of righteous person fighting for justice. Like his personality, his fighting style is also the opposite of Mitsuhashi's: he's incredibly tough, and often stands up from any beating, even in the most bleak of situations. While he may be as strong as Mitsuhashi, Itou is beat up much more often than Mitsuhashi due to often sacrificing himself to protect others as well as fighting fair in unfair situations or against numerable opponents. He dates Kyoko.
